We're hiring PhD-level experts to help train and evaluate advanced AI models.

This is a short-term engagement running through the end of June, with potential to extend depending on project needs.
Key Responsibilities
You May Contribute Your Expertise By
- Assessing the factuality and relevance of domain-specific text produced by AI models
- Crafting and answering questions related to Machine Learning and AI
- Evaluating and ranking domain-specific responses generated by AI models
